QUV Light Accelerated Weathering Testers for Automotive Exterior Materials and Coatings
QUV Light Accelerated Weathering Testerscan simulate the sun, rain and dew to damage the material, QUV using UV lamp simulate the effect of sunlight, cold rain and dew. Being tested materials are placed in a certain environment which the light and moisture are alternating.UV lamp can simulate the effect of the sun, condensation and water spray system can simulate the effect of rain and dew. the temperature can be controlled at the process of testing. A typical test cycle is usually testing at UV radiation of high temperature and the 100% humidity at dark; Typically used in paint and coatings, automotive, plastic products, wood products, glue, etc.
Application
It is widely used in paint, resins, plastics, printing and packaging, aluminum, adhesives, auto, cosmetics, metals, electronics, electroplating, medicine, etc.
